[PATCH 3/8] scsi: scsi_dh_alua: Pass submit_rtpg() a bool for extended header support

[John Garry <john.g.garry@oracle.com>]

Currently the pg flags is passed to submit_rtpg() to allow submit_rtpg()
know whether extended header support is available.

Pass a bool instead, as when separating the driver into a pure ALUA part,
we don't want to use pg flags.
